BACKGROUND: Nonocclusive disease (NOD) is known to be a common cause of ischemic colitis, which is frequently underestimated. MATERIAL AND METHODS: A computer-assisted search of radiological reports at our institute over a period of 18 months, describing ischemic colitis of the ascending colon with an unimpaired perfusion of the superior mesenteric artery, was performed. RESULTS: A retrospective analysis of the clinical and radiological data of 14 patients was performed. In ten cases colonic ischemia was confirmed clinically or intraoperatively. Most of our patients needed intravenous catecholamines due to severe hypotension. However, no significant radiographic predictors could be identified. CONCLUSION: Awareness of NOD seems to be crucial. Especially in cases of acute abdominal pain associated with severe hypotension, renal insufficiency, or pancreatitis, one should include NOD as a differential diagnosis at an early stage.
Stump appendicitis is an acute inflammation of the residual appendix and one of the rare complications after appendectomy. Paying attention to the possibility of stump appendicitis in patients with right lower abdominal pain after appendectomy can prevent the delay of diagnosis and treatment. In patients with stump appendicitis, CT scan not only assists in making an accurate preoperative diagnosis but also excludes other etiologies. We report a 47-year old man with preoperatively diagnosed stump appendicitis by CT, who underwent an open appendectomy 20 years ago.
We present a case of a 37-year-old woman who presented with acute right lower quadrant abdominal pain. Work up with contrast enhanced CT to rule out appendicitis revealed dramatic ring enhancing cystic structure in the right adnexa corresponding to tubal ring sign of ectopic pregnancy seen on subsequent pelvic ultrasound. Right tubal ectopic pregnancy was confirmed at surgery.
